ORNAMENTING ENAMELED OR GLAZED SURFACES.

SPECIFICATION forming part of Letters Patent No. 309,910, dated December 30, 1884.

Application filed December 5, 1883. (Specimens) I same has dried such as adheres to the surface To all whom it may concern.-

Be it known that I, HENRY ABBOTT, of Newark, in the county of Essex, and in the State of New Jersey, have invented certain new and useful Improvements in Ornamenting Enameledor Glazed Surfaces; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to certain improvements in the method of ornamenting enameled or glazed surfaces, heretofore made by me, in which vitrifiable colors are filled into the sunk portions of engraved or etched plates, and fluid collodion then flowed over the sur- 5 face of the plate and caused to permeate and become incorporated with said colors. which eollodion, after hardening, is removed in the form of a film having upon its face the design in color. The film thus produced is afterward used as a transfer medium for said design to the surface of the article to be ornamented,

when by the application of heat the vitrifiable color becomes incorporated with such surface.

In the carrying out of my said method the vitrifiable color has been applied to the plate in the manner usual in plate-priutingthat is, by means of a pad or the hand of the operator; but the result has not always been satisfactory, as the lines, more especially the hcav 0 lines, would sometimes be imperfectly filled,

and the colored enamel, when burned in, present a lumpy appearance, with ragged edges of some of its lines.

To obviate this defect and to insure full sharp lines in the completed design when transferred is the objectof my present invention, which consists, principally, in the method employed for producing transfer-films, substantially as hereinafter specified.

0 It consists, further, in the plate employed for receiving and containing the colored material, substantially as and for the purpose hereinafter shown.

In the carrying into effect my invention a 4 5 plate, preferably copper, has engraved or etched within its surface the desired design, care being had that the heavy lines have substantially uniform depths, and that their bottoms are flat and smooth. Over the prepared surface of the plate thusformed is evenly spread a coat of colored paint having for its body any of the vitrifiable materials such as are used in encaustiopainting, and after the is removed, leaving the lines or sunk portions 5 5 filled with said colored material of a uniform thickness. The plate is now placed in ahorizontal position and liquid collodion flowed over its face and caused to permeate and become incorporatedwith the colored material within the sunk portions, after which said collodion is permitted to harden, and is then removed from the plate, taking with it the colored design.

It is found that by my method each portion of the design is perfectly formed, and when transferred to and burned into the surface of the article to be ornamented such design has all of the sharpness and fidelity of the original engraving. 7o

\Vhile the plate having flat bottoms of its heavy lines is preferably employed, my meth- 0d of filling in the color may be satisfactorily used upon plates engraved in the usual manner. 7 5

Having thus fully set forth the nature and merits of my invention, what I claim as new l. The method of producing transfer-films, consisting, first, in filling the lines and coat- 8o ing the surface of an engraved or etched plate with liquid colored material, and permitting the same to dry, then removing the colored material from the surface of said plate, leaving its lines filled, then flowing over said surface liquid collodion, and causing the same to permeate and become incorporated with said colored material, and, lastly, permitting said collodion to harden, and then removing the same, with its adhering or incorporated design, in the form of a film, substantially as specified.

2. As a means for producing transfer-films,

a plate having engraved, etched, or otherwise formed in intaglio within its surface a design the heavy lines of which have flat smoothbottoms, substantially as 'and for the purpose shown.

In testimony that I claim the foregoing I have hereunto set my hand this 4th day of De- 10o cember, A. D. 1883.

HENRY ABBOTT.
